Like any harmonious family, we have a shared vision, shared values, and share our services to better support our clients. We make decisions in the best interest of the entire family and support each other to grow in both good and challenging times. Detailed mobility data makes it possible to understand where walking and cycling happens today — and where new investments could prompt even more of it. Policy dictates what a local jurisdiction finds “acceptable” in terms of corner design and when trade-offs are permitted.

Truck aprons must balance challenging objectives and finding which designs perform better is critical for moving toward a future standard. For example, an early theme that emerged in our case studies is that significant vertical profiles (5 inches [13 cm] or higher), are much more effective at deterring passenger vehicles than ones that are flush with the pavement or lower. In one case study, mountable aprons built to a 2 inch (5 cm) height had to be rebuilt to 6 inches (15 cm) because passenger vehicles were turning over them.

She desires to learn more about the intersection of technology, policy, and planning to promote a greener future. Teresa aspires to bring her data analytics experiences to Alta and learn how geospatial data science can improve urban infrastructure and decision-making, while also ensuring civic engagement and equity. As an avid user of shared bikes and e-scooters during her travels around the world, she is looking forward to acquiring knowledge from micro-mobility and active transportation projects and further solidifying her data analysis skills. Maisie MacNaughton has joined the Alta Canada team as an Engineering Intern based in Toronto, ON for the next 16 months. She is currently pursuing a Bachelor’s degree in Civil Engineering from the University of Toronto, where she has resided her entire life.

Her areas of passion encompass climate adaptation and mitigation, public health, and the design of urban green spaces, all of which have a deep connection to active transportation systems. Throughout her internship at Alta, she aspires to explore the intersections of design and planning, actively engage with communities, and acquire knowledge about the practical opportunities and challenges involved in active transportation projects. When Alta Planning + Design helps public agencies plan for active transportation and safe streets, they turn to Replica data to identify where investments are likely to have the greatest impact.
Featured Projects
Replica’s data on land uses and trips allowed Alta to develop an understanding of what mobility activity looks like on a typical day in these areas. Mobility hubs can also be a first, low cost phase for testing mobility options and iterative placemaking and investment. The elements of sidewalk design include transportation, “outdoor living room” amenities and utilities.
Alta pioneered the field of active transportation, evolving their planning and design work into a visionary global practice that empowers people to live active, healthy lives and gets them to where they need to go. With 200 staff located across the US and Canada, Alta is dedicated to connecting people to places by working across disciplines and scale to address social justice, safety, and environmental resilience. Alta was founded in 1996 when communities were calling for safer streets for people walking and bicycling as the non-motorized transportation movement developed in North America. Alta pioneered the field of active transportation, evolving our planning and design work into a visionary practice that empowers people to live active, healthy lives and gets them where they need to go. With over 200 staff located across the US and Canada, Alta has evolved its practice into a forward-thinking sustainable transportation company, backed by the Trilon Group.
Alta’s Expansion: A New Era in Transportation Demand Management Planning and Behavior Change
Their Civic Analytics team works with transportation professionals across the USA and Canada to help communities use data to inform how investments in human-scaled transportation can help advance multifaceted community goals. Alta works to mitigate climate change and advance safety and social justice through sustainable mobility. We connect people to places by providing solutions across the disciplines of planning, design, engineering, education and encouragement programs, and community engagement. Lidet Bayou is a recent graduate from the University of Minnesota, where she studied Urban Studies and minored in Architecture and Sustainability Studies. Through her studies and past work experiences, she has gained hands-on experience in transportation planning and community engagement with local government agencies and non-profit organizations in the Twin Cities.
Community Infrastructure

Founded in 1976, Waggoner has a proud history of delivering infrastructure solutions, with a focus on the Water market. They share a common vision with Trilon in that they do more than plan and design infrastructure – they help transform communities. Hubs range from simple co-location of several modes (e.g. bus stop, private shuttle stop, bike share station, and bicycle racks) to larger districts where land uses, infrastructure and mobility options (existing and emerging) are strategically planned together.
Soozy is a Master of Landscape Architecture student at Cal Poly Pomona, holding an undergraduate degree in Civil Engineering. During her time completing her engineering degree at San Jose State, she realized her desire to gain a deeper understanding of the interaction between people, nature, and engineering systems. She possesses a strong passion for fostering environments where individuals and the environment can flourish harmoniously. A key aspect of this is enhancing bicycle and pedestrian infrastructure in urban areas to promote increased access to both active transportation and green spaces. Soozy aspires to apply her interdisciplinary skills at Alta, while also acquiring knowledge of sustainable and human-centered design principles. Portland, OR – August 24, 2022 – Today Alta Planning + Design, Inc. (Alta) announced a strategic partnership with Trilon Group (Trilon), a family of infrastructure-focused businesses.
MSG is a premier multi-disciplined consulting firm, serving an exclusive collection of the some of the best and fastest growing private entities, municipalities, and governmental agencies across the Americas. With Replica data, Alta developed an interactive map that shows the origins and destinations of bicycling and walking trips, as well as trips less than three-miles-long that could conceivably be served by walking, bicycling, or other micromobility options. “Combining the trip and land use data, we’re able to see that people are walking in rural areas, challenging assumptions about where the needs are for pedestrian infrastructure,” lead project planner Maria Wardoku says.
With this in mind, Alta decided it was time to instigate a more focused discussion on corner design, through a lens of finding strategies that work for all users. Alta’s newest white paper, Corner Design for All Users, offers a collection of innovations in the design of intersection corners in a way that balances the need to accommodate large vehicles while providing safety for pedestrians and cyclists. HMB is a premier provider of engineering services primarily focused on state and local agency clients in the transportation, water and environmental markets.

Alta is a part of the Trilon Group, a family of companies focused on growing infrastructure capabilities to better serve our clients through investments in talent, technology and targeted mergers and acquisitions. When investing in active transportation, it’s important to know where people are walking and cycling. It’s also critical to understand where people could be walking and cycling if new infrastructure prompts them to change how they travel short distances. For years, design guidance, including that from FHWA and AASHTO has provided tools and direction to transportation engineers to make intersections more compact and slow turning speeds. Despite this, few communities have figured out how to balance these principles while maintaining access for large design vehicles.
They work on projects throughout the continent and have offices in Atlanta, Denver, Los Angeles, and Toronto. Since 2000, UrbanTrans has been at the forefront of TDM, leading with a mission to create sustainable environments and advance innovative transportation solutions through a people-first approach that ensures impactful results at every scale. Aswatha has recently earned a Master’s degree in Urban and Regional Planning at Portland State University. She obtained her Bachelor’s degree in Architecture from Anna University in Chennai, India, and gained experience collaborating with architects and real estate developers, designing structures influenced by local vernacular building techniques.
Alta found that the City of Toronto’s Curb Radii Guideline to be among the most flexible and forward thinking policies across Canada and the US. The document dictates the allowable turning paths for large vehicles based on the context of the intersection, and sets an upper corner radius limit of 15 metres (49 feet), above which special approval is required. In addition, the City of Toronto provides a map of large truck turning volumes at every intersection in the city, to reduce the need for on-site data collection.
